基于地理信息可视化的线状符号表达方法的研究

The Method of Linear Symbol Expressing Based on Geographic Information Visualization

本文根据线状要素地理信息表达的需要 ,对线状符号进行了分类 ,在分析了线状符号的视觉变量之后 ,给出了其图案单元的数据结构。最后结合线状符号的分解。

The linear symbol is classified according to the demand for symbol expressing, besides the data-structure of pattern cell of linear symbols is given combining with its visual variable. The paper bring forward the method of placement for linear symbols based on the characteristic of decomposition and combination about pattern cell of linear symbol.
